BASIC OF NETWORKING:(newbie edition 1)
hello there , this is newbie again :)
previous post : i discuss about i just cureently enrolled cisco basics of networking course,i was learning still now ,and i share my learnings and understanding in networking…..ok let’s start
THE INTERNET is not owned by any individual or group.The internet is a world wide collection of interconnected networks (internetwork or short form of internet)cooperating with each others to share or exchange informations and data ,thorough the telephone wires, fiber-optic cables, wireless- transmitter and satelites links,internet users can exchange info in a variety of formships.
small home networks connect a few computer to each other and to the internet.the SOHO (small office and home office) network allow the computer in the home office or a remote office to connect to the corporate,There are devices all around that you may interact with on the devices such as smartphones,tablets,smart watches,and smart glasses also :0.Things in your home can be connected to the internet such as security system,appliances,your smart TV ,and your gaming console.Outside your home there are smart cars,RFID tags ,sensors and actuators,and even medical devices which can be connected.network or access centralized,shared resources.
Medium to large networks,such as those are used by corporates and schools ,colleges,can have many locations with hundreds of thousands of interconnected hosts.
but my opinion is if you are learn about network , you just start in the small things like small devices like mobiles,laptop,pc etc. That was the good start to learn about networking and it’s an easy way to learn about them.And one more point , When you just enroll an new course and learn along the way , one the other hand do your own searches on that ,for getting an grasp of knowledge about them.
Finally [[[[[[ INTERNET is a network of networks that connects of millinons of computers world-wide.]]]]]]
the data is almost anywhere and everywhere ,likewise our data also given by ourselves for specific reasons ,and taken by otherselves for most of the situations.In the way personal data were important to a person .
the following categories are used to classify types of personal data:
volunteered data — this is created and explicitly shared by individuals,such as social network profiles.for example in your instagram you just post your photos, edited stories with cool captions :) ,and scroll the instagram you liked the specific reels , and put likes and comments on the sarcasmic memes and videos something like that .that was an perfect example of volenteered data.Second example when you’re skilled in specific things and you want to share knowledge to others wih the help of social media ,those are the education contents also come under the volenteered data.This type of data might include video files, pictures, text, red or observed data.
Observed data — This is captured by recording the actions of individuals, such as location data when using cell phones. Observed data that was like when you want purchase an specific things on amazon,you should to log in first ,to visit that site and give your home address ,location,phone numbers to purchase an product ,this type of data was called as an Observed data.
Inferred data — This is data such as a credit score, which is based on analysis of volunteered or observed data.This is basically an Hybrid of both volenteered and Observed data,when google was an perfect example for the inferred data ,basically Google just analyse your search history,get that data in your searches ,and shows the relevent ADS for your compatapility,This is also relevent to the Digital Footprints.
Ok …. we talk about data for the very long time,Now we discussed about what actually computers are known about data ,Basically computer’s are unaware of your data’s,searches etc…They only known about 0's and 1's
The term bit is an abbreviation of “binary digit” and represents the smallest piece of data.
Each bit can only have one of two possible values, 0 or 1.Those are the data were computer should known still now ;
NOW, I have an some idea’s about what types of data are exists,and what types of data computers are known about….etc,and now i tell you ,how data were transfered from one device to another devices ,actually that point was the networking were started.. 🙌Certainly computers are uses signals to communicate with other devices,in Networking terms they called as transmission media.
There are three common methods of signal transmission used in networks:
Electrical signals — Transmission is achieved by representing data as electrical pulses on copper wire.
Optical signals — Transmission is achieved by converting the electrical signals into light pulses.
Wireless signals — Transmission is achieved by using infrared, microwave, or radio waves through the air.
Bandwidth is the capacity of a medium to carry data.
Digital bandwidth measures the amount of data that can flow from one place to another in a given amount of time.
Bandwidth is typically measured in the number of bits that (theoretically) can be sent across the media in a second.
Common bandwidth measurements are as follows:
Thousands of bits per second (Kbps)
Millions of bits per second (Mbps)
Billions of bits per second (Gbps)
Throughput does not usually match the specified bandwidth. Many factors influence throughput including:
The amount of data being sent and received over the connection
The latency created by the number of network devices encountered between source and destination
Latency refers to the amount of time, including delays, for data to travel from one given point to another.This was the just an basic level of computer networking ,hope this blogs gives an atleast small amount of ideas to you ,if my content was good , give me an rise 👍and give an connect request to my linkedin : https://www.linkedin.com/in/ajrunafsana/
